The average MPG for the 535 is 23mpg, while for the 550 is 20mpg. So there is only 3mpg average difference. But I would guess that during normal everyday driving the power difference would be very very minimal. Those who have tested both could probably advice better on that.
Personally, I would pick 535i with more options such as ZPP, ZCW, ZSP+paddles and ZDH. What is the difference in options added to each?
